Wonderful! Thanks so much for your kind words and detailed answers, Ben. I truly appreciate your patience and openness to work through this together.
From your reply, we're likely dealing with a missing or incompatible driver, or interference from third-party software.
Here's what you can do to isolate and resolve the issue.
Step 1. Visit ASUS Support page to install or update Chipset & Bluetooth Drivers
https://www.asus.com/support/
While this is not a Microsoft website, it is the official site of your device manufacturer.
Download and install the latest drivers for the following:
AMD Chipset Drivers
Bluetooth Driver
Wi-Fi/LAN Driver (for stability)
After installing, reboot your PC even if you're not prompted to.
Step 2. If possible temporarily uninstall interfering apps
Some tools like DS4Windows, BetterJoy, or older drivers might conflict with Nintendo controllers.
Press Windows + R, type appwiz.cpl, and press Enter
Temporarily uninstall your DS4Windows, BetterJoy and any controller remapper you don’t currently need
Also, go to Device Manager > View > Show hidden devices
Expand Bluetooth, HID, and Universal Serial Bus controllers
Right-click and uninstall any grayed-out or unknown devices
Then reboot.
Step 3. Try reconnecting the controller
Use a known good USB-A to USB-C data cable
Connect it directly to a rear USB 3.0 port
Check Device Manager again (especially HID)
For wireless: Go to Settings > Bluetooth & devices > Add device > Bluetooth
If “Pro Controller” shows up, try pairing.
Step 4. Optional BIOS Check. You mentioned you can’t access BIOS, just confirming, are you pressing Del or F2 during the first logo screen? If it's fast booting too quickly, try holding Shift + Restart > Troubleshoot > Advanced options > UEFI Firmware Settings to reboot directly into BIOS.
There we can check, If Bluetooth is enabled or if there's an S5 deep sleep option (some users disable this to improve controller support)
Let me know how it goes after the driver updates and cleanup. I’m here to help you until this gets resolved. You’re doing great so far!
